W512 module with green substrate and a tan plastic extraction handle, attached by two rivets. Handle reads "DIGITAL EQUIPMENT CORPORATION MAYNARD, MASSACHUSETTS" in raised letters. Most of the above text is covered by a white oval sticker that reads "DEC 78 8125870 CS" in blue. An incised "3" is visible in the handle , just left of the sticker. The reverse side of substrate (with solder joints) reads "P.L.C. W512A" along the edge. Obverse side is covered by a variety of components. "FLIP CHIP" can be read through substrate, under two inspection stamps, between the rivets. A repeating "neLco" pattern in red print is visible on the substrate.
